The correct determination of cup orientation in THA regarding the intraoperative as well as the postoperative assessment due to the pelvic tilt and rotation with inexact incorporation of the pelvis is uncertain. The anterior pelvic plane (APP) seems to be the most reliable reference frame and computer-assisted navigation systems seem to provide the best tool for correct implantation to date. For the intraoperative assessment of the APP, the exact determination of the bony landmarks is mandatory. For the standard plain radiography, standardized positioning of the patient and approximation of pelvic tilt by a lateral view are mandatory. An additional CT must be carried out for certain indications. More emphasis has to be given to the individuality of pelvic tilt and range of motion.
由于骨盆倾斜和旋转以及骨盆整合不准确,在全髋关节置换术中正确确定髋臼方向以及进行术后评估存在不确定性。骨盆前平面(APP)似乎是最可靠的参考框架,而计算机辅助导航系统似乎是迄今为止实现正确植入的最佳工具。对于术中评估APP,必须准确确定骨性标志。对于标准的X线平片,患者的标准化体位以及通过侧位片评估骨盆倾斜度是必要的。对于某些适应症,必须进行额外的CT检查。必须更加重视骨盆倾斜度和活动范围的个体差异。
